Corryn Rayney

The trial judge closely examined Evidence on the conduct of Lloyd Rayney and reportedly described him as a barrister who had engaged in "disreputable conduct" in comments which were redacted from the final official judgment (para 1594), and Justice Martin noted that "The accused has engaged in discreditable conduct including knowingly arranging for illegal telephone interception, making a false declaration and giving deliberately false Evidence to a court while on oath. The Evidence raises suspicion; in some instances quite strong suspicion. But discreditable conduct does not prove guilt, and suspicion, even strong suspicion, falls well short of proof beyond reasonable doubt."

The Judgment Summary further explained: "Evidence concerning such conduct was not admitted to show that the accused is a person of bad character. The fact that the accused engaged in discreditable conduct and could, therefore, be viewed as a person of bad character, cannot be used to reason that the accused is the type of person who might kill his wife, or that by reason of his bad character he is likely to have killed her. Such reasoning would be unfair and is prohibited."

Corryn Veronica Ann Rayney, née Da Silva, (born 1963) migrated to Australia with her Indian family in 1973 as refugees from Idi Amin's Uganda.

The Rayneys lived in the Perth suburb of Como and had two daughters, Caitlyn (born 1994) and Sarah (born 1997).

At the time, Lloyd Rayney was involved in a Corruption and Crime Commission inquiry into the misconduct of police officers in a murder investigation.

Corryn Rayney was employed as a registrar at the Supreme Court of Western Australia.

Her vehicle, a 2005 Ford Fairmont, was also missing.

On 14 August, her car was found abandoned on a residential street in Subiaco.

Police subsequently followed an oil leak to Kings Park, where they located her body on 16 August in a shallow grave off Lovekin Drive.

It was announced the police would be treating her death as a murder inquiry.

Her funeral was held on 1 September.

At the trial of Rayney's husband, forensic doctor John Hilton and neuropathologist Victoria Fabian both testified that the cause of death was not clear, but that she had sustained injuries to her head, neck and brain.

Fabian testified that the injuries indicated some form of neck restraint had been employed, though not to the point of strangulation, and that the injuries were not sufficient to cause death.

She noted that the bleeding had been found between Rayney's intervertebral discs, which only occurred in cases of traumatic injury.

Hilton testified that this bleeding could have arisen from a combination of compressive forces and rabbit punches to the back of the neck.

However, he also stated that "he could not exclude the possibility Mrs Rayney received her neck injuries as she was placed head-first into her bush grave at Kings Park", although they definitely occurred prior to death and there was little to suggest that she had been alive at the time of burial.

He further stated there was no Evidence of drugs or poison in her system.

The prosecution also presented Evidence that the Rayneys' marriage had broken down irretrievably due to Lloyd Rayney's affairs and gambling habits, having lost nearly $50,000 to Centrebet between April 2006 and July 2007.

It was alleged that she had recently "put her husband on notice that if he did not disclose his finances, she would have his clients, from whom he received legal fees, subpoenaed", and that he had been secretly recording her phone calls and conversations.

Her death occurred on or about 7 August 2007, her body being discovered a week later in a clandestine grave in Kings Park, Perth, with no clearly established cause of death.

Her husband Lloyd Rayney, a prominent barrister specialising in criminal prosecution, was charged with her murder, but found not guilty after a trial before a judge only.

She was last seen alive at 9.30 p.m. on 7 August 2007 at a boot scooting class.

A week later, police discovered her abandoned car and followed a trail of oil from it to the grave in Kings Park.

Rayney was reported missing on 8 August 2007, having last been seen at her weekly boot scooting class in Bentley the previous night.

Although Lloyd Rayney was controversially described by the chief police investigator Senior Sergeant Jack Lee as the "only suspect" at a police press conference in September 2007, he was not charged with the murder until December 2010, more than three years after the event.

At the request of the defendant in October 2011, the trial was heard by a judge only, with no jury.

The reasons for the application were suppressed at the time, but later published in March 2012.

Lloyd Rayney wanted a trial without a jury, on the grounds that the extensive publicity would make a fair jury trial impossible to achieve.

The decision to conduct the trial without a jury was a subject of debate in Australian legal circles.

Former Northern Territory Chief Justice Brian Ross Martin was appointed as an Acting Justice of the Western Australia Supreme Court in February 2012 to preside over the trial; a judge from outside Western Australia being used to ensure impartiality, given that both the victim and accused had held senior legal positions in the state.

The trial began on 16 July 2012.

An affidavit filed by the prosecutors indicated that the case was circumstantial.

The prosecutor's opening address to the trial said that the state's case was circumstantial but the Evidence of motive was compelling.

The prosecution hypothesised that Lloyd Rayney had killed his wife at the family home in Como, then dragging her along the driveway to her car, driving to Kings Park, burying her body, abandoning her car, and returning home.

The circumstantial Evidence presented included a dinner place card with Lloyd Rayney's name found near the burial site, brick dust and soil that was allegedly consistent with being dragged along a driveway, and liquidambar seed pods found in her hair that were alleged to match a tree at the family home which was not present in Kings Park.

The trial ran until 19 October 2012 when final submissions were presented by prosecutor John Agius QC and defence counsel David Edwardson QC.

On 1 November, Justice Martin acquitted Lloyd Rayney when he handed down a judgment of not guilty, saying that the "case by the State is beset by improbabilities and uncertainties".

The full reasons for the verdict were published, a requirement which would not have applied to a jury verdict.

The acquittal was unanimously upheld by a court of appeal in August 2013.

The state's police commissioner and attorney general declined to acknowledge documented procedural mistakes, and refused to instigate a fresh search for the killers, leading to calls for a federal investigation into the matter.
